The company already makes the Lumia range of handsets which are aimed at everyday customers, and so it makes sense that Microsoft wants to focus on business when it comes to the Surface Phone.

The Surface Phone, which has been repeatedly hinted at by Microsoft, will likely continue where the Surface tablets left off, incorporating metallic, angular design and business-focused accessories, such as the Surface Pen.

It's no secret that Microsoft's mobile ambitions are in serious trouble, with just 75 million Windows phones in the wild, according to data from Gartner and IDC. However, Microsoft still has a more-than-loyal following in enterprise thanks to tight integration with Outlook, Office, and Lynk (formerly Skype for Business).

Big companies will typically buy thousands of Windows phones for employees — and then thousands more after a few years — and so continuing to service these users both validates the existence of Windows 10 Mobile and the company's hardware efforts as well as complementing Windows 10.
